Other examples of a medical system message may include but are not limited to EMR to EMR communications, or information transferred, generated, created, and/or accessed in relay health type systems that manage patient communications, and other type of medical messaging and/or communication between any types of systems.

The disclosure herein provides methods, systems, and devices for managing, transferring, modifying, converting and/or tracking medical files and/or medical system messages. In certain embodiments, the foregoing may generally be based on requesting medical files at a first medical facility, identifying the requested medical files at a second medical facility, initiating a secure network connection between the first and second medical facility, modifying a header portion of the medical files based on patient identification information created by the first medical facility, and other processing steps.

With the development of new technologies, medical images and/or records are increasingly created and stored electronically. Electronic medical images and records data are in certain instances reviewed by medical personnel on a picture archiving and communication systems (PACS), which are computers and/or networks dedicated to the storage, retrieval, distribution and presentation of medical images and records. Generally, the medical images and records data are stored in an independent format, wherein the most common format for storing medical images, and in some cases medical records, is DICOM (Digital Imaging and Communications in Medicine).

In certain PACS, there is software and/or hardware that prevents doctors from viewing multiple electronic files containing medical images and records wherein the electronic files are associated with different patient identification numbers. Such patient identification numbers, also known as a medical record numbers (MRN), are generally stored in the header portion of the medical images and/or records files. This is generally a safety mechanism that prevents medical professionals from comparing data from two different patients. This mechanism operates effectively when each patient possesses one identification number.

In certain instances, patients have multiple identification numbers because patients often visit multiple hospitals or other medical facilities. For example, patients move from one locality to another; or patients seek second opinions from doctors at different medical facilities; or patients visit different doctors specializing in different medical fields as patients move through various stages of life or treatment. Generally each doctor and/or medical facility has a unique patient identification numbering scheme or system.

Accordingly, a patient's medical images and/or records at one facility are associated with one patient identification number whereas the same patient's medical images and/or records at another facility are associated with a different patient identification number. Therefore, PACS that have the safety mechanism described above prevent medical professionals from conducting a side-by-side review of the medical images and/or records associated with different identification numbers even though the images and/or records correspond to the same patient. A medical professional using a PACS in conjunction with the methods, systems, and devices described herein can conduct a side-by-side review of the medical images and/or records associated with different identification numbers provided, however, that the images and/or records correspond to the same patient.

In one embodiment, medical facilities are equipped with a system that allows each facility to transfer medical files from a source medical facility to a destination medical facility. During the transfer of the medical files, the system is configured to dynamically change or add or modify the patient identification information in the header portion of each medical image and/or record file to the patient identification information that the destination medical facility has assigned to the patient. After changing, adding, or modifying the patient identification information in the header portion, the medical image and/or record files are stored in the medical facilities databases for medical professionals to review and analyze these files through a PACS or other workstation computer. By modifying the patient identification information in the header portion, a PACS or other workstation will recognize that the newly stored files correspond to the patient's previously stored files, and therefore a PACS or other workstation will allow medical professionals to conduct a side-by-side analysis of the newly stored files with the previously stored files.

FIG. 1 is a block diagram illustrating a high level overview of one embodiment of a medical image and record files transfer system 100. In the depicted embodiment, a first medical facility 102 is connected through a network 210 to a plurality of other medical facilities 106, a kiosk system 108, and a main server system 110.

The network 210 may include one or more of internet connections 112, secure peer-to-peer connections, secure socket layer (SSL) connections over the internet, virtual private network (VPN) connections over the internet, or other secure connections over the internet, private network connections, dedicated network connections (for example, ISDN, T1, or the like), wireless or cellular connections, or the like or any combination of the foregoing. In a preferred embodiment, the medical facilities are connected to each other through a mesh network 300 wherein each medical facility is capable of connecting to every other medical facility through an on-demand, and/or ad-hoc, and/or available when needed, and/or non-persistent, permission based SSL or VPN or other secure connections over the internet, as shown in FIG. 3.

In one embodiment, the web interface and the film librarian interface 120 do not directly connect to the client server system 124 to ensure network security of the client server 124 and the other medical facility servers. In general, the firewall 122 operates to limit and/or reduce access to files stored within a computer network, such as the local area network (LAN) generally existing at each medical facility, from remotely located machines. In other embodiments, the firewall 122 is within the client server system 124.

A kiosk system 108, or a plurality of kiosks, connects to the network 210 to communicate with the main server system 110, and to allow patients to interact with the main server 110. In certain embodiments, the kiosk system 108 or like systems can be configured, for example, to allow patients to generate requests for medical files to be transferred from one medical facility/medical professional to another medical facility/medical professional, and/or allow patients to provide approval for transferring medical files from one medical facility/medical professional to another medical facility/medical professional. For example, the kiosks 108 allow patients to submit to the main server system 110 HIPAA (Health Insurance Portability and Accountability Act) release forms, which are necessary to allow one medical facility to release medical records to another medical facility. The main server system 110 is configured to connect to the kiosk 108 to receive HIPAA release forms and store the forms in the HIPAA release form database 140 located in the main server system 110. The main server system is configured to verify the receipt of an executed HIPAA release form before releasing medical files, and, in certain embodiments, the main server system 110 is configured to send a copy of the HIPAA release form to the source medical facility such that copy of the form can be stored in the HIPAA release form database 136 at the source medical facility. In certain embodiments, the main server system 110 is configured to transfer an executed HIPAA release form to a destination medical facility for storage.

Generally, the kiosk system 108 comprises a computer having memory and a storage medium, a display, a keyboard, and a network connection. In certain embodiments, the kiosk system 108 comprises a scanner for scanning and creating a digital file of HIPAA release forms received from patients. In other embodiments, the kiosk system 108 comprises an input device configured to allow patients to write and input their signature into the kiosk system 108 thereby providing authorization to release their medical files. In other embodiments, the kiosk system 108 comprises a camera for obtaining a digital image of a patient using the kiosk system 108 thereby allowing for visual verification of the patient that is releasing medical files to another medical facility. In certain embodiments, the kiosk 108 is a home computer, personal computer, handheld device, or other user access point.

The main server system 110 connects to the client server systems 124 at the medical facilities and the kiosk systems 108 through the network 104. In a preferred embodiment, the main server system 110 comprises but is not limited to a web server 142, an authentication module 144, a transfer history database 138, a billing module 146, a HIPAA release form database 140, and a medical facility keys database 148. In certain embodiments, the main server system 110 can be configured, for example, among other things, to: act as a central authentication manager that allows client server systems 124 to communicate with other client server systems 124; control a work flow process for transferring patient medical files, examinations, and other data between medical facilities; build a knowledge database that facilitates the locating and/or transferring of medical files, examinations, and/or other data; and/or enable billing processes for each transfer of medical files, examinations, and/or other data. In certain embodiments, medical facilities encryption keys database 148, the transaction history database 138, and/or the HIPAA release form database 140 are different tables within the same database.

The web server 142 may comprise, for example, an Apache HTTP Server configured to serve web pages and web applications. In a preferred embodiment, the web server 142 operates to provide and interact with the web interface and the film librarian interface 120 at the medical facilities. In other embodiments, the web server 142 operates to provide and interact with patients using a kiosk 108. The web server 142 is configured to receive requests for medical files and direct the request to the authentication module for further processing. Based on the request, the authentication module 144 identifies the medical facility that the request should be sent to and pushes the request through the web server 142 to be displayed on the film librarian interface 120 such that the film librarian can review the request.

If the film librarian approves the request, the approval is sent through the film librarian interface 120 to the web server 142, which directs the approval to the authentication module 144 for further processing. The authentication module 144 then sends a communication to the client server system 124 at the source medical facility, wherein the communication comprises an instruction to send the requested medical files to the destination medical facility. The authentication module 144 also sends a communication to the client server system 124 at the destination module, wherein the communication comprises an instruction to receive the requested medical files from the source medical facility.

In a preferred embodiment, the communication sent by the authentication module 124 to the client server systems 124 at the destination and source medical facilities also comprise a network security key for establishing a secure network connection between the two client server systems 124. In certain embodiments, the client server systems 124 are configured to establish secure network connections sequentially or simultaneously wherein each connection uses a different network security key provided by the main server system 110. In certain embodiments, the security key provided by the main server system 110 is only or is generally valid for one use and/or for a specific period of time. Alternatively, the security key can be recycled after a period of time of non-use, and still be unique or substantially unique to allow for secure communications and/or connections. In certain embodiments, it is the authentication module 144 that determines the number times and/or the expiry of the network security key. If a transfer of medical files fails to occur, the destination and/or the source medical facilities sends a communication to the main server system 110, reporting that the medical image files were never sent and/or received. The authentication module 144, in certain instances, is configured to send another communication to the client server systems 124 at the destination and source medical facilities, wherein the communication comprises a new network security key and an instruction to send/receive the requested medical files.

The authentication module 144 also operates to record the date and time of the transfer authorization, the medical facilities involved in the transfer, the medical files transferred, and other related transfer history data into the transfer history database 138. The authentication module 144 also operates to communication/signal the billing module to bill the appropriate party for the transfer. In a preferred embodiment, the billing module 146 bills the source medical facility for each transfer of medical files. The billing module 146 can also be configured to bill the destination medical facility for each request and/or transfer of medical files into the destination medical facility. The billing module 146 can also be configured to generate a bill/invoice or transmit a bill/invoice over a network connection or through regular mail to any other party, such as an insurance company, third party invoice processing center, or the like. The billing module 146 can be configured to generate and/or transfer bills/invoices on a real time basis substantially with the completion of the transfer of medical files, or on a periodic basis, a batch basis, or the like. The billing module 146 can also be configured to generate a bill/invoice based on a per transaction/transmission basis or a subscription model.

In certain embodiments, the medical facility keys database 148 stores medical facility keys used by medical professionals to access the transaction history database 134 and the HIPAA release form database 136 stored in the client server systems 124 located at the medical facilities.

Human and/or Electronic Process

FIG. 4 is a simplified example of one embodiment of requesting and transferring medical image and record files using the medical files transfer system of FIG. 1. At block 400 a medical professional at a first medical facility makes a request for at least one medical file by completing a request form through the web interface. The first medical facility is also known as the destination medical facility because the medical file will be transferred to the destination medical facility. In contrast, the medical facility that receives the request for the medical file is also known as the source medical facility.

On the request form, the medical professional provides patient information related to the patient, and medical facility information related to both the destination and source medical facilities. For example, the patient information may comprise, but is not limited to, the patient's name, the patient's identification number at the destination medical facility, the patient's identification number at the source medical facility, the patient's age, sex, disease type, address, date of birth, social security number, or the like. The medical facility information may comprise, but is not limited to, the name of the medical facility, identification number of the medical facility, the location of the medical facility, the division or branch office of the medical facility, the telephone number of the medical facility, or the like. In one embodiment, the PACS, RIS, HIS, and/or other local hospital systems can comprise the same functionality as the film librarian interface such that the PACS, HIS, and/or other local hospital systems can be configured to automatically generate a request for medical files, wherein the request is sent to the main server system an application programming interface (API). For example, a doctor reviewing medical files on a PACS can in-context (meaning while reviewing medical files for a particular patient) generate a request for related medical files that are available at other medical facilities by using the interface of the PACS. In certain embodiments, the generated request from PACS, RIS, HIS, and/or other local hospital systems can submitted, transmitted, and/or communicated through a http:// or https:// connection, or URL request/message, internet connection, wireless connection to the main server, the client server system, and/or the film librarian interface system. In certain embodiments, the generated request from the PACS, RIS, HIS, and/or other local hospital systems can be transmitted, communicated, and/or submitted through a messaging protocol (for example, HL7) over any kind of network.

The web interface sends the patient information and the medical facility information to the main server, wherein the main server system determines where the request should be sent. After identifying the appropriate medical facility (the source medical facility) to send the request, the main server system at block 404 sends the request to the film librarian interface corresponding to the source medical facility.

In a preferred embodiment, the film librarian or other medical personnel at block 406 reviews the request on the film librarian interface, and attempts to locate and match the patient name and source patient identification number provided in the request form. In certain circumstances, the medical professional searches a PACS, a RIS, a HIS, or the like to locate medical files associated with the information provided in the request form. In certain embodiments, the system semi-automatically and/or automatically conducts a search and/or matches the patient name and source patient identification number provided in the request form and/or searches a PACS, a RIS, a HIS, or the like to locate medical files associated with the information provided in the request form. In certain embodiments, the system presents or causes to display match information (for example, exact and/or near matches) to the film librarian for review and/or approval and/or selection. The medical professional then determines whether the source medical facility possesses medical files corresponding to the provided patient information.

If the medical professional locates and matches the provided patient information with medical files at the source medical facility, the medical professional approves the request form by interacting with the film librarian interface. The film librarian interface sends the approval communication as well as the matching information to the main server at block 408. The matching information can comprise but is not limited to the patient identification number assigned by the source medical facility, and/or names or other identifications to locate the requested medical files. At block 410, the main server system then instructs the client server system at the source medical facility to send, transmit, or transfer the appropriate medical record files to the client server system located at the destination medical facility. At block 412, the main server system also instructs the client server system located at the destination medical facility to receive, access, accept, or retrieve the appropriate medical files from the client server system at the source medical facility.

In other embodiments, the main server system stores or saves the matching information for future use. For example, if a future request is received by the main server system, and the request comprises substantially the same or similar patient information and/or medical files/examinations, and/or MRN's, the main server system can be configured to automatically match and/or locate the requested medical files based on the previously saved matching information and/or user-configurable matching criteria and/or other algorithm. For example, the main server system can be configured to build over time a knowledge database of matching patient identification numbers, MRN's, locations of medical files/examinations, or the like. In certain embodiments, the knowledge database is generated or updated periodically or in real time based on data mining of the Transaction History Database or by querying various attached and/or connected client server systems at medical facilities. Using the knowledge database, the main server system can be configured to send, transfer, or cause to display a listing of all or substantially all the medical files/examinations at all or substantially all the medical facilities equipped with a client server system. For example, for a specific patient identification number used by one medical facility, the main server system can be configured to generate a listing of all known patient identification numbers assigned to the patient at other medical facilities, and generate a listing of all or substantially all known medical files/examinations available at the various medical facilities. In certain embodiments, the knowledge database is generated from data received and/or stored in the client server system. In other embodiments, the main server system is configured to generate the listing information by retrieving the patient information from the multiple client server systems in real time or periodically based on a batching process.

In other embodiments, the locating and matching is performed automatically by the main server system or the client server system, and not by a medical personnel operating through a film librarian interface. In this embodiment, the main server system is configured to send a request for medical files to the client server system at the source medical facility. The client server system automatically attempts to match and/or locate the medical files associated with the patient information provided in the request form via user-configurable matching criteria and/or other algorithm. In searching for the medical files, the client server system connects to the medical facility's PACS, image server, RIS, HIS, or other database system where patient medical files are stored.

If a match that satisfies a minimal threshold is found, then the request form is approved automatically by the client server system, and/or may be presented, displayed to the film librarian for approval, and a communication is sent back to the main server. The main server system then instructs the client server system at the source medical facility to send the appropriate medical record files to the client server system located at the destination medical facility. The main server system also instructs the client server system located at the destination medical facility to receive the appropriate medical files from the client server system at the source medical facility.

Accession Number Creation

To track medical files received at a destination medical facility, accession numbers are created for each medical file received. The accession number not only tracks the medical file within a medical facility, but also an accession number is used to link related portions of a medical file that are related but stored in different databases. For example, an accession number can link a medical image stored in the image database with a corresponding doctor's report that is stored in a RIS and/or HIS system because the same accession number has been stored in the header portion of both medical image file and the doctor's report file.

In one embodiment, after the medical file has been transferred from the source medical facility to the destination medical facility, the client server system directly creates an accession number in the RIS and/or HIS and/or PACS systems at the destination medical facility, wherein the accession number relates to the medical files that have been received. In other embodiments, the accession number is created before the medical files have been transferred but after the client server has instructed by the main server system to receive medical files from another medical facility.

In one embodiment, the process of creating an accession number occurs directly between the client server system and the RIS and/or HIS and/or PACS system when the client server system has full and open access to the RIS and/or HIS and/or PACS systems. Where the client server system does not have full and open access to the RIS and/or HIS and/or PACS system, the client server system, in certain embodiments, is configured to create an Order Message (ORM), or equivalent message or the like, that is sent to the RIS and/or HIS and/or PACS systems, which causes the RIS and/or HIS and/or PACS systems to create an accession number for the medical files that were received, and returns the accession number to the client server system.

In the HL7 Standard, an ORM message is any request for materials (for example, 500 ml of 2.5% saline) or services (for example, a range of motion study, an EKG, a lipid panel, and the like). Orders are usually for a particular patient. The transmission of clinical orders occurs between the application placing the order (the placer) and the clinical application filling the order (the filler). Accordingly, the placer in this embodiment is the client server system at the destination medical facility and the filler is the RIS and/or the HIS system at the medical facility.

Header Modifications and Image Conversions

The client server system at the destination medical facility is configured to modify the header portion of the medical files to ensure that the medical files are compatible with the patient identification numbering system, and the other systems at the destination medical facility. In certain embodiments, the client server system modifies the header portion of the medical files by removing, modifying, substituting, or, adding the patient identification number that corresponds to the source medical facility and inserts, modifies, substitutes, or, adds the patient identification number utilized by the destination medical facility.

In certain embodiments, the client server obtains the patient identification number from the RIS and HIS systems associated with the destination medical facility. In some embodiments, the client server obtains the patient identification number from the main server system. In certain embodiments, the main server system provides this information while instructing the client server system at the destination medical facility to receive, retrieve, access, or accept medical files from the source medical facility. In other embodiments, the client server system at the source medical facility modifies the header portion of the medical files to comprise the patient identification number provided by the destination medical facility, wherein such modification at source medical facility can occur prior to the transfer of the medical file from the source to the destination medical facility.

In some instances, the destination medical facility provides the patient identification number directly to the source medical facility. In other instances, the patient identification number is provided to the source medical facility by the main server system. In other instances, the client server system at the source medical facility is configured to transfer a raw medical data file without a header portion, wherein the client server system at the destination medical facility is configured to add a header portion comprising information compatible with the PACS and other systems of the destination medical facility.

In certain embodiments, the client server system at the destination medical facility is configured to confirm the medical files into a format that is compatible for the PACS and other systems at the destination medical facility. For example, the client server system is configured to convert a DICOM medical image file into a JPEG medical file. Alternatively, the client server system may convert a DICOM medical image file with the image compressed in JPEG2000 to a format compatible with the target PACS or other system such as a DICOM image compressed in standard JPEG.

The client server system and/or the remote server system is configured to store the received medical files and/or examinations in the PACS, image server, RIS and/or HIS systems at the destination medical facility. A medical professional can then retrieve and view the medical files from the PACS, RIS and/or HIS systems at the destination medical facility. In certain embodiments, a user at the destination medical facility can view medical files obtained from the source medical facility side-by-side with the medical files from the destination medical facility. In certain embodiments, the client server system is configured to also store the received medical files in a patient data database within the client server system to enable medical professionals to retrieve and/or review medical files and/or examinations directly from the client server system without retrieving the information from the PACS, image server, RIS, and/or HIS systems. The client server system can be configured to store the medical files and/or examinations indefinitely or for a temporary period of time, for example, minutes, hours, days, months, or years. In certain embodiments, the client server system can be configured to control, store and/or remove medical files and/or examinations based on a policy that can be fixed and/or amended.

Transaction History Information

In one embodiment, the client server system comprises a transaction history database for tracking the transfer history of medical files. For example, the client server system is configured to record in the transfer history database the transfer of every or substantially every medical file that is transferred in and/or out of its medical facility, and such information is known as transaction history information as defined above. In certain embodiments, the transaction history information is associated and/or is assigned a unique identifier in a lookup table or the like so that the foregoing information can be recalled based on the unique identifier. The unique identifier or a reference tag is then embedded or written or stored in the header of the medical file to a form an audit trail thereby allowing medical professionals or others to later determine the origins of the file.

In certain embodiments, the client server system is configured to decipher or interpret at least a part of the foregoing unique identifiers. For example, the client server system can identify the medical facility that created the unique identifier. Based on that information the client server system and/or a medical professional can search or request to have searched the transfer history database of the medical facility that created the unique identifier to obtain the transfer history information associated with the medical file.

Instead of storing a unique identifier in the header portion of a medical file, in another embodiment, the transaction history information itself is written or added into the header portion of the medical file as text or in another data format every time or substantially every time the medical file is transferred from one medical facility to another thereby creating an audit trail. If transaction history information is in text, the transaction history information can be written with or without tags (for example, XML, HTML, and the like). In certain embodiments, the PACS or other system is configured to allow a medical professional to review and analyze the transaction history information stored in the header portion of the medical file, using a header viewer system.

In other embodiments, the client server system is configured to analyze, interpret, normalize, and/or filter the transaction history information in the header portion of a medical file, and directly store the information in RIS and/or HIS systems when the client server system has direct and open access to the RIS and/or HIS systems. In other embodiments, where the client server system does not have open and direct access to the RIS and/or HIS system, the client server system creates an Observation/Results Message (OBX), or equivalent message, system communication, or the like, comprising the transaction history information and an accession number, and sends the OBX message, or equivalent message, system communication, or the like, to the RIS and/or HIS systems which accepts and processes, and stores the message. Normalizing, as used herein, can comprise but is not limited to a method or system of analyzing the data, extracting certain recognized data elements, and assigning those data elements to a particular related data field used by the system.

In other embodiments, the transaction history information is transferred in the data portion of a medical file instead of the header portion of a medical file. The transaction history information can be stored as text in the data portion of the medical file with or without tags (for example, XML, HTML, and the like), or the transaction history information can be stored as an image in the data portion of the medical file. If stored as an image file, then the client server system is configured to modify the header portion of this medical file as disclosed herein and store the medical file in the PACS and/or image server.

In certain embodiments, the PACS and/or other systems are configured to allow a medical professional to review and analyze the transaction history information stored in the data portion of the medical file as a normal medical image or record file. PACS and/or other systems can also be configured to compare and/or review the transaction history information as an image with other medical files because the patient identification numbers do not conflict and/or are the same after the client server system inserts, overwrites, amendments, adds, and/or modifies the correct patient identification number to the header portion of the medical files.

In any transfer of medical files and/or examinations, there may be multiple series of medical files, images, reports, and/or examinations in the set. For example, a set may include without limitation a series of scout views, a series of brain window images, a set of bone window images, and/or the like. In certain embodiments, a transaction history information summary image 1200 may appear with separate series and/or set. For example, as illustrated in FIG. 12, a transaction history information summary image 1200 can be displayed at the beginning, the end, and/or at any other point of each series. In other embodiments, the transaction history summary images 1200 may appear at the beginning, end, and/or at any other point in the set. In other embodiments, the client server system is configured to analyze, interpret, filter the transaction history information in the data portion of a medical file, normalize the transaction history information, and store the normalized transaction history information in RIS and/or HIS systems at either a destination or source medical facility.

If the transaction history information is stored as text in the data portion of a medical file, then the client server system is configured to analyze, interpret, normalize, and/or filter the transaction history information in the data portion of a medical file, and directly store the information in RIS and/or HIS systems when the client server system has direct and open access to the RIS and/or HIS systems. In certain embodiments, the storing of the transaction history information in the RIS and/or HIS systems occurs by inserting the information into specific related entry fields when the client server system has open and/or complete access to the RIS and/or HIS systems.

In other embodiments, where the client server system does not have open and direct access to the RIS and/or HIS system, the client server system creates an OBX message, or equivalent message, system communication, or the like, comprising the transaction history information and an accession number, and sends the OBX message, or equivalent message, system communication, or the like, to the RIS and/or HIS systems which accept and process, and stores the message. Normalizing, as used herein, can comprise but is not limited to a method or system of analyzing the data, extracting certain recognized data elements, and assigning those data elements to a particular related data field used by the system. and/or the RIS/HIS systems as a medical file. The OBX, or equivalent message, system communication, or the like, can comprise at least the patient identification number used by the destination medical facility, the accession number and the transaction history information and the name of the medical file associated with the transaction history information.

In the HL7 Standard, an OBX is a message used to transmit a single observation or observation fragment. One mission of an OBX is to carry information about observations and results. Sometimes, the OBX segment is found as a part of an order message (ORM or RDE). In this case, the OBX carries clinical information needed by the receiving system. For example, an OBX is needed to report the menstrual phase information which should and/or could be included on an order for a pap smear to a cytology lab. The OBX message or segment can be used to contain encapsulated data, for example, a PDF document, a CDA document or a DICOM image or any of the MIME (Multimedia Internet Mail Extension) support formats such as JPEG, GIF, FAX, and the like. If the actual observation value is not sent in an OBX but exists somewhere else, the OBX message or segment can contain a reference pointer. The reference pointer can be a hyperlink which the receiving system would use to access the observation information, document, or image. The OBX segment can be used to transmit patient clinical information in a variety of formats.

In other embodiments, the client server system is configured to transfer the transactional history information by electronic mail after receiving instructions from the main server system.

Medical History Information

Transaction history information differs generally from medical history information as is defined above. In certain embodiments, the medical history information is transferred from one medical facility to another in the data portion, as opposed to the header portion, of a medical file using the various transfer methodologies described herein. The client server system at a destination medical facility is configured to receive to the medical file comprising the medical history information. In some instances, the medical history information is stored as text with or without tags (for example, XML, HTML, and the like); however, the medical history information can also be stored as an image.

If the medical history information is stored as text, then the client server system at the destination medical facility is configured to analyze, interpret, normalize, and/or filter the medical file comprising the medical history information, and/or directly store the medical history information into the RIS and/or the HIS system located at the destination medical facility. In certain embodiments, the storing of the medical history information in the RIS and/or HIS systems directly occurs by inserting the information into specific related entry fields when the client server system has open and/or complete access to the RIS and/or HIS systems.

If the client server system does not have open and/or complete access to the RIS and/or HIS systems, the client server system, in some instances, is configured to create OBX, and/or equivalent message or system communication or the like, comprising the medical history information, and sends the OBX, and/or equivalent message or system communication or the like, to the RIS and/or HIS systems such that the medical history information can be stored in the RIS and/or HIS systems at the destination medical facility. The OBX, and/or equivalent message or system communication or the like, can comprise at least the patient identification number used by the destination medical facility, the accession number, and the medical history information.

If the medical history information is stored as an image, then the client server in certain embodiments stores the image in the PACS and/or image server or RIS or HIS, assuming the target system can accept image data. The client server system is configured to modify the header portion of the medical file that comprises the medical history information by inserting or adding to the header portion the patient identification number used by the destination medical facility. In certain embodiments, the client server system is configured to directly store the modified medical file comprising the medical history information in the PACS and/or image server. In other embodiments, the client server system is configured to directly store the modified medical file in RIS and/or HIS systems where the client server system has direct and/or full access to those systems. If the client server system does not have direct and/or full access to those systems, then the client server system creates an OBX, or equivalent message, system communication, or the like, that can comprise the image, and sends the message to the PACS, RIS and/or HIS systems for processing and storage. Medical professionals with access can use PACS, RIS, and/or HIS systems thereafter to view the medical file side-by-side with other medical files for that patient stored at the medical facility because the patient identification numbers stored in the header of the medical files do not conflict and/or are the same.

In the foregoing embodiment, the medical history information can also be inserted into the header portion of the medical file instead of the data portion of a medical file. The client server system at a destination medical facility is configured to receive to the medical file comprising the medical history information in the header portion of the medical file. In some instances, the medical history information is stored as text with or without tags (for example, XML, HTML, and the like). In certain embodiments, the client server system at the destination medical facility is configured to analyze, interpret, normalize, and/or filter the header portion comprising the medical history information, and/or directly stores the medical history information into the RIS and/or the HIS systems located at the destination medical facility where the client server system has direct and/or full access to those systems. If the client server system does not have direct and/or full access to those systems, then client server system creates an OBX, or equivalent message, system communication, or the like, that comprises the medical history information, and sends the message to the RIS and/or HIS systems for processing and storage.

In other embodiments, the client server system is configured to transfer the medical history information by electronic mail after receiving instructions from the main server system.

FIG. 5 depicts a detailed example of one embodiment of requesting and/or transferring medical image and/or record files using the medical image and record files transfer system of FIG. 1. At block 502, a medical professional enters a request for an exam or medical file by using the request form interface as illustrated, for example, in FIG. 6. As disclosed herein, the request form interface can take on various forms, and preferably, the request form interface is a web interface accessible from most any computer or device with network access to the web server in the main server system. The information provided by the medical professional comprises but is not limited to facility location, patient name, date of birth, last four digits of the patient's social security number, DL, approximate date of examination and/or medical file creation, examine type, body part examined, and the like.

Concurrently or sequentially, at block 504 patient completes and submits a HIPAA release form. A patient can use a kiosk system, or other user access point at the destination medical facility (or at some other location) completes and/or submits a HIPAA release form for allowing the requested medical files to be released. In certain embodiments, there is a unique bar code on the HIPAA release form to uniquely identify the HIPAA release form or to associate the HIPAA release form to a particular patient. In certain embodiments this HIPAA release form may be computer generated and downloadable from the internet or in other embodiments may be printed by the kiosk. As disclosed herein, the kiosk system or a hospital/medical facility workstation attached and/or electronically connected to the client server system can accept a paper form completed by the patient. After accepting the HIPAA release form, the kiosk can scan and/or OCR the paper form (into a PDF, TIFF, or other document/image file format) at block 506, and identify the bar code or other information on the form. In certain embodiments, the bar code is already associated with the patient, in which case, the kiosk can associate the scanned paper form with the correct patient and transfer the scanned paper form to the main server system for storage in the HIPAA release form database. In certain embodiments, the bar code is not already associated with the patient, in which case, the kiosk system instructs that the user input identification information (name, contact information, username, and/or identification code, or the like), and kiosk system verifies the information with the main server system. If the patient information is verified, then the kiosk system associates the patient identity (for example, the main server system's unique identifier, the patient identification at the source medical facility, the patient identification at the destination medical facility, or the like).

Alternatively, at block 508, the HIPAA release form can be faxed to an electronic facsimile (fax) system or other computer system that can digitize and process the fax. At block 510, the fax system can have OCR integrated into the system so that the fax system can read, interpret, and/or decipher the bar code on the HIPAA release form, thereby allowing the fax system to automatically associate the faxed HIPAA release form with the proper patient and/or request.

Alternatively, the kiosk system can allow the patient to complete the form electronically via the interface on the kiosk system. In certain embodiments, the kiosk system is configured to comprise a signature pad, wherein the patient can write or input his signature to be electronically stored in a database at the kiosk system, or in the main server system, or in the client server system at a medical facility, or printed on to a HIPAA release form. To verify the identity of the patient, the signature can be compared to prior signatures on file by the main server system or by the film librarian. The kiosk can also comprise a webcam or other video/photo input device for capturing a video or photographic image of the patient using the kiosk. The video or photographic image can be used by the film librarian to verify the identity of the patient.

In other embodiments, the kiosk system is a computer accessible by the patient, or other device accessible by the patient, such as but not limited to a handheld computer with network access to the main server system. Such computers or devices can include without limitation all or some of the features of the kiosk set forth above. Alternatively, the patient and/or the medical professional can fax, email, or otherwise transfer the HIPAA release form to the main server system for storage in the HIPAA release form database.

As disclosed herein, the main server system receives the executed HIPAA release form and the request for medical files, and matches the HIPAA release form to the request by optical character recognition (OCR) software, corresponding bar codes, or other methodology of linking the form with the request. At block 512, the main server system stores the request for medical files in the transfer history database and stores the HIPAA release form in the HIPAA release form database. At block 514, using the various methods and systems disclosed herein, the main server system displays the request for medical files on a film librarian interface at the appropriate source medical facility. At block 516, a film librarian at the source medical facility reviews the request for medical files, and at block 518 uses the RIS and/or HIS interfaces available to the film librarian to identify the patient and at block 520 to locate the requested examination or medical files.

In certain embodiments, the main server system is configured to compare, using OCR software or other recognition software, the signature on the HIPAA release form to signatures previously received, stored, or recorded in the HIPAA release form database to verify the identity of the patient. The main server can also compare the photographic image or video with previously stored photographic images or videos to verify the identify of the patient. The foregoing verification steps can also be completed by the film librarian.

At block 522, if no examination or medical files that correspond to the information in the request form exist or are available, then the film librarian selects the option “no films were available” using the film librarian interface. At block 524 and 526, the response is then sent from the film librarian interface to the main server system, and the main server system displays the response on the film librarian interface at the destination medical facility, notifying the medical professional that the requested medical record file could not be found. Alternatively and/or additionally, the main server system is configured to send an email or other notification to the medical professional that created the request for the medical file. In certain embodiments, the email can be encrypted and/or protected using other secure protocols and/or means for protecting the confidential data within the email. The email can also be configured to comprise a hyperlink to a secure website (for example, requiring a username and password, encryption key, authentication and/or the like) in order to obtain, retrieve, and/or review the confidential data and/or information.

If the examination or medical files that correspond to the information in the request form do exist or are available, then the film librarian selects the option “approve” using the film librarian interface. In certain embodiments, at block 528 the film librarian interface displays the approval form wherein the film librarian enters the medical record number (MRN) into the approval form as disclosed herein and submits the information. The approval information is sent to the main server system, and the main server system sends the information to the client server system at the source system to perform a search for the medical files corresponding to the MRN's provided by the film librarian. For example, at block 530 the client server system at the source medical facility performs on a PACS and/or an image server at the source medical facility a DICOM query for examinations related to the MRN's provided by the film librarian.

If the medical records are located at the source medical facility, the main server system is notified and at block 532 the main server system displays on the librarian interface at the source medical facility the information relating to the medical files located at the source medical facility. Using the film librarian interface at block 534, the film librarian selects the examination and/or the medical files appropriate for transfer to the destination medical facility. These selections are sent from the film librarian interface and sent to the main server system, and at block 536 the main server system sends the information to film librarian interface at the destination facility so as to notify the medical professional that requested the medical files. Alternatively and/or additionally, the main server system is configured to send an email or other notification to the medical professional that created the request for the medical file.

The main server system also sends the information about the located medical files to the client server system at the destination medical facility. In certain embodiments, at block 538 the client server system performs a check to determine whether the PACS, RIS and/or HIS systems or other medical systems at the destination medical facility have ORM, and/or equivalent message or system communication or the like, capabilities.

If there are no ORM capabilities, and/or equivalent order capabilities, and/or other electronic order creation capabilities, the client server system at block 540 sends a communication to the main server system, and the main server system relays the communication to the film librarian interface the destination medical facility, instructing the film librarian to manually create an order, and/or a no read order, in the RIS and/or HIS system at the destination medical facility. The RIS and/or HIS system creates an accession number to be associated with the medical files being transferred to the destination medical facility. The film librarian at the destination facility is then presented with a list of exams available for the selected patient. This list may aggregate available studies from multiple medical facilities or may present only studies from one source medical facility, based upon whether the initial request was to one or multiple facilities or all known facilities. The destination film librarian can then select the exams and/or medical files that are appropriate and desired for transfer. At block 542, for the each exam and/or medical files selected for transfer, the destination film librarian uses the film librarian interface to select the request at issue and inserts the accession number in the request form. The film librarian interface sends that information to the main server system, and the main server system sends the information to the client server system at the destination medical facility.

If there are ORM, and/or equivalent message or system communication or the like, capabilities, the film librarian at the destination facility can then be presented with a list of exams available for the patient. This list may aggregate available studies and/or medical files from multiple medical facilities or may present only studies and/or medical files from one source medical facility, based upon whether the initial request was to one or multiple medical facilities. At block 544, the destination film librarian can then select the exams and/or medical files that are appropriate and desired for transfer. At block 546, the client server system can then create an ORM, and/or equivalent message or system communication or the like, and sends it to the RIS and/or HIS system at the destination medical facility for each exam selected. The RIS and/or the HIS system receives the ORM, and/or equivalent message or system communication or the like, creates and accession number to be associated with each of the medical files, and returns to the client server the accession number for each file. In one embodiment, at block 548, the client server system retrieves the accession number from the RIS and/or HIS system after each ORM, and/or equivalent message or system communication or the like, has been sent.

In certain embodiments, the film librarian and/or the medical professional that created the request for the medical files selects the desired medical files from those that are available, and such selection is made through the film librarian interface in some instances. In other embodiments, the medical files are automatically transferred from the source destination medical facility.

In certain embodiments, after the accession number has been created and has been obtained by the client server system at the destination medical facility, the client server system sends a communication to the main server system, and at block 550 the main server systems sends a communication to the client server system at the source medical facility, wherein the communication comprises an instruction to initiate a network connection with the destination medical facility and send the requested medical files to the destination medical facility.

In certain embodiments, the communication comprises without limitation, the instruction to retrieve selected medical files from a PACS, and/or an image server, HIS system, and/or MS system, instructions to transfer medical files to the destination medical facility, the medical record number, the patient identification number used at the source medical facility, the medical facility identification number of the destination medical facility, the network location of the client server system at the destination medical facility, and/or a network key/encryption key for establishing a secure network connection with the client server system at the destination medical facility. In certain embodiments, the network key/encryption key is only valid and/or usable for a specific period of time, and/or can only be used once. Alternatively, the network key/encryption key can be recycled and/or reused after a period of non-use.

A similar communication is sent from the main server system to the client server system at the destination medical facility, wherein the communication comprises an instruction to accept and/or establish a network connection with the source medical facility to receive the requested medical files from the source medical facility.

In certain embodiments, the communication to the client server system at the destination medical facility comprises without limitation, the instruction to locate the accession number to be associated with the medical files, instructions to receive the medical files from the source medical facility, the patient identification number used at the destination medical facility, the medical facility identification number of the source medical facility, the network location of the client server system at the source medical facility, and/or a network key/encryption key for establishing a secure network connection with the client server system at the source medical facility.

In other embodiments, the client server system is configured with an interface device for receiving medical files from a portable storage media instead from the source medical facility through a network connection. For example, a portable storage media may comprise but is not limited to a CDROM, DVD-R, Blu-ray, USB or other memory stick, floppy diskette, a magnetic tape, or the like. In other embodiments, the client server system is configured with or is connected to an email server, wherein the client server system is configured to receive medical files through email as an attachment or a link to a network storage server or the like.

After the medical files have been received by the client server system at the destination medical facility, at block 552 the client server system, in certain embodiments, is configured to modify the header portion of the medical file to insert or add data as disclosed herein. For example, the client server system can be configured to insert or add or replace as appropriate the following information into the appropriate fields of the header portion of transferred medical files: the new medical record number used by the destination medical facility, the new accession number used by the destination medical facility, the patient identification number used by the destination medical facility, the transaction history information to record the transfer of the medical record file from the source to the destination medical facility; the old accession number used by the source medical facility, the old accession number used by the source medical facility, or any other information.

At block 554 and block 556 the client server system is configured to then store the medical record files in the appropriate database. For example, if the medical record is a DICOM image then the client server system may be configured to store the medical file in the PACS and/or image server at the destination medical facility. In other instances the medical file is a text file or a PDF file comprising a report or analysis of a medical image file, and the client server system is configured to store the medical file in the PACS, RIS and/or the HIS and/or other system at the destination medical center. As disclosed herein, the storing of the medical file in the RIS and/or the HIS system can occur directly between the client server system and the RIS/HIS system, or by the client server system creating an OBX, and/or equivalent message or system communication or the like, comprising the medical file and sending the OBX, and/or equivalent message or system communication or the like, to the RIS/HIS system for processing and storage.

In other embodiments, the client server system at the source medical facility sends the requested medical files to destination medical facility. After receiving the medical files, the client server system at the destination medical facility creates an ORM, and/or equivalent message or system communication or the like, and sends it to the PACS, RIS and/or HIS or other medical system to generate an accession number for each exam received. The PACS, RIS and/or HIS or other medical system receives the ORM, and/or equivalent message or system communication or the like, creates the accession number to be associated with each of the medical files, and returns it to the client server. The client server at the destination medical facility modifies, inserts, replaces the accession number in the header of the medical file with the newly generated accession number received by the client server system.

FIG. 6 depicts an example of one embodiment of a screen view 600 of the request form interface associated with requesting medical files through the medical image and record files transfer system of FIG. 1. The screen view can take on various forms, such as an HTML-based web interface, a java applet, a Windows interface, or the like. As disclosed herein, the requesting screen view is connected to the main server system through the network.

As disclosed herein, the film librarian interface screen view is connected to the main server system through the network.

In this film librarian interface screen view 700, the film librarian at the source medical facility is provided information related to incoming requests 702 for medical files as well as the status of outgoing requests 704 for medical files that were created by medical professionals at the source medical facility. For example, in the top portion of the screen, the film librarian is presented with incoming requests 702 for medical files from various medical facilities. The film librarian can scroll 706 through the incoming requests wherein certain information is displayed, such as the unique identification number of the request 708, the date and time of the request 710, the requesting institution 712, the city 714, state 716, and status of the request 718, or the like. For example, the status of a request could be but is not limited to new, approved, denied, and not found. The film librarian can click on any one of the requests to review the detailed information about the request.

The film librarian can utilize the request information displayed on the film librarian interface 700 to cross reference with other database interfaces accessible at the source medical facility to search for the requested medical files. If the film librarian does not locate the medical files, the film librarian can select the files not found button. If the film librarian does locate the records but the HIPAA release form cannot be located or is invalid, then the film librarian can select the denied button. If the film librarian does locate the records and the HIPAA release form can be found and/or is valid, then the film librarian hits the approve button, which launches a new screen window as shown in FIG. 8.

FIG. 8 depicts an example of one embodiment of a screen view 800 associated with approving a request for medical files through the medical image and record files transfer system of FIG. 1. The screen view 800 can take on various forms, such as an HTML-based web interface, a java applet, a Windows interface, or the like. As disclosed herein, the approving screen view that is part of the film librarian interface is connected to the main server system through the network.

In this approving screen view 800, the information about the request for medical files and the related patient information is displayed. For example, the information comprises but is not limited to institution state 806, institution name 804, patient name 812, 814, 816, the patient identification number used by the source medical facility 808, the patient identification number used by the destination medical facility 810, the date of birth of the patient 818, the patient phone number 820, the medical files being requested (for example, by description, by accession number, by date and type), and at least a portion of the patient's social security number 822. The film librarian can also insert, input, and/or append information about the available or located medical records available for transfer 828. For example, the film librarian can input information such as accession number 830, date 832, description of the medical file 834, and modality the medical file exists 836, or the like. In certain embodiments, the system can automatically and/or semi-automatically populate, input, insert, and/or write information into the approving screen view for the film librarian to review and/or approve 838. The film librarian can also insert notes to be viewed by the medical profession at the destination medical facility.

After completing the approving form, the film librarian selects the approve button and the approval information is sent to the main server system. In certain instances, the main server system is configured to send instructions to the client server system at the source medical to send the specified medical files to the destination medical facility, and to send instructions to the client server at the destination medical facility to accept the medical files from the source medical facility. In other embodiments, the main server system is configured to present the available medical files to the film librarian at the destination medical center, wherein the film librarian at the destination medical center can select which medical files should be transferred from the source medical facility. After the medical files are selected on the film librarian interface at the destination medical facility, the selection information is sent from the film librarian interface to the main server system wherein the server system sends instructions to both the client server systems at the source and destination medical facilities as set forth above.

FIG. 9 depicts an example of one embodiment of a header portion 900 associated with a medical image or medical record file. In the header portion of a medical file, various fields can exist, for example, patient name 902, patient identification number 904, patient social security number, the medical facility that created the image or record 932, audit trail 938, medical history information, or the like. In the audit trail field, the client server system, in some embodiments, is configured to insert or add transaction information. In the medical history information field, the client server system, in some embodiments, is configured to insert or add medical history information.

With reference to FIG. 10, an example of the medical procedure mapping module 1002 is depicted in the main server system. The medical procedure mapping module 1002 can be used to map, translate, or rename the code and/or name of a medical procedure performed at a first medical facility 1004 into the procedure code and/or name used by a second medical facility 1006. As illustrated in FIG. 10, Medical Facility 1 1004 has performed scan of Patient 32412 1008, and the procedure name for the scan is CT Abd/Pelvis w/IV Contrast 1010, which means Patient 32412 had a CT scan of his abdomen and pelvis areas with IV contrast added. Patient 32412 has authorized Medical Facility 2 1006 to access his scan; however, Medical Facility 2 1006 has a different patient identification number 1012 for the patient, and uses a different name for the medical procedure that was performed, for example, Abd/Pelvis CT w/1014.

Accordingly, and still with reference to FIG. 10, the code and/or procedure name of the scan can be changed within the header portion of the patient file for purposes of ensuring that the file is compatible with the medical systems at Medical Facility 2 1006, enabling medical professionals at Medical Facility 2 1006 to determine the contents of the medical file, conforming the file name to the consistent naming standard of Medical Facility 2, ensuring the association of the proper billing codes and/or medical reimbursement codes to the medical file, or the like. The remapping or renaming protocol can be a one-to-one mapping or a many to one mapping, or one to many mapping. For example, a one-to-one mapping is where each code and/or name of a medical procedure is mapped to one specific code and/or name. In contrast, a many-to-one mapping is where several codes and/or names of medical procedures are mapped to one specific code and/or name.

In certain embodiments, the system is configured to map medical procedure codes and/or names at destination and/or source medical facilities to a standardized mapping table and/or a standardized intermediary code system. By using a standardized mapping table and/or a standardized intermediary code system the complexity of maintaining separate mappings for each institution can be reduced. The original procedure name and/or code may in certain embodiments be stored in a DICOM tag or private DICOM tag in the header and/or displayed as in a summary image saved, stored, embedded, or burned into the image set. In certain embodiments, the medical procedure mapping module automatically maps, translates, and/or renames the source procedure code and/or name to the code and/or name of the medical procedures used at the destination medical facility, possibly through the standardized intermediary code system described above, and stores the data in the PACS, RIS and/or HIS systems at the destination medical facility.

Regarding FIG. 10, in certain embodiments, the medical procedure mapping module 1002 is located at the medical facility in the client server system 1004. After receiving the medical file from Medical Facility 1 1004, the client server system at Medical Facility 3 1016 processes the header portion of the medical file using the medical procedure mapping module. The medical procedure mapping module identifies the “CT Abd/Pelvis W/IV Contrast” code 1010 and/or name of a medical procedure performed Medical Facility 1, and maps, translates, and/or renames it to the code and/or name of the corresponding medical procedure performed Medical Facility 3, which in this example is “Abd/Pelvis CT” 1014. In the foregoing example, a one-to-one mapping is used, wherein medical procedure codes and/or names at one medical facility map directly to medical procedure codes and/or names at another medical facility.

Referring to FIG. 10, alternatively, the medical procedure mapping module located at the source medical facility, in this example, Medical Facility 1 1004, can be configured to use the medical procedure mapping module to map, translate, and/or rename the medical procedures to the corresponding codes and/or names in a standardized mapping table and/or standardized intermediary code system stored at the main server system 1018. The standardized mapping table and/or standardized intermediary code system can be accessed in the main server 1018 in real-time or a copy of the standardized mapping table and/or standardized intermediary code system can be transferred, distributed, or pushed out periodically to the client server systems so that the information can be accessed locally and without accessing the main server 1018. The mapped, translated, and/or renamed the medical procedure having the standardized nomenclature can be transferred to the destination medical facility, for example, Medical Facility 2 or 3. The client server system at the destination medical facility medical, for example, Medical Facility 2 or 3, can use the procedure mapping module and the standardized mapping table to map, translate, and/or rename the medical procedure having the standardized nomenclature to the codes and/or names used by the destination medical facility. In the foregoing example, medical procedure codes and/or names at one medical facility are mapped first to a standardized mapping schema or table, and then the standardized mapping codes and/or names are mapped to the multiple medical procedure codes and/or names at other medical facilities

Referring to FIG. 10, the medical procedure mapping module can also be configured to allow a medical professional, with the appropriate authorization and/or system privileges, to manually review, analyze, approve, override, set, and/or identify the code and/or name of the medical procedure to be associated with the medical file. The setting chosen by the medical professional can be temporary (for example, a special code or name for the medical file) or can be stored for similar medical files received in the future. As such, the medical procedure mapping module can be configured to remember and/or save the setting manually performed or selected by the medical professional so that similar medical files received in the future will automatically be associated with the code and/or name of the medical procedure. Accordingly, the medical procedure mapping module can learn over time the proper codes and/or names to be associated with certain medical files, or build a mapping table over time. Alternatively, the medical procedure mapping module can be configured with a mapping table during the initial setup or during periodic updating of the client server system and/or the main server system.

In some embodiments, the acts, methods, and processes described herein are implemented within, or using, software modules (programs) that are executed by one or more general purpose computers. The software modules may be stored on or within any suitable computer-readable medium. It should be understood that the various steps may alternatively be implemented in-whole or in-part within specially designed hardware. The skilled artisan will recognize that not all calculations, analyses and/or optimization require the use of computers, though any of the above-described methods, calculations or analyses can be facilitated through the use of computers.

Marking Medical Files/Examinations “Signed”

With reference to FIG. 11, when importing medical files and/or examinations from a source medical facility to a destination medical facility, the transferred medical files and/or examinations are generally listed in a work list as a new medical file and/or examination for a medical professional to review, analyze, and process; however, such transferred medical files and/or examinations have generally been reviewed and analyzed by a medical professional at the source medical facility. To review and analyze a new medical file and/or examination, it is processed over several stages, for example, approved, unread, read, preliminary interpretation, and/or final interpretation/signed steps. To ensure that already reviewed and analyzed medical files and/or reports do not go through the foregoing processing stages, the client server system can be configured to use an Observation Result (ORU) message, and/or equivalent message, system communications, or the like, to properly mark the medical files and/or examinations as “signed” or electronically signed (process 1100).

Referring to FIG. 11, in the HL7 Standard, an ORU is usually in response to an order and provides clinical observations. In HL7 messaging, ORU messages provide structured patient-oriented clinical data between systems (for example, EKG results to a physician's office). ORU messages also can be used for linking orders and results to clinical trials (for example, new drugs or new devices). Clinical observations can include without limitation: clinical laboratory results, imaging studies (for example, text), EKG pulmonary function studies, and/or interpretations, and/or the like.

Regarding FIG. 11, in certain embodiments, the client server system can be configured to use an ORU message, and/or equivalent message, system communication, or the like, to set a flag or status flag in a PACS, RIS, HIS, and/or other system, or to trigger a PACS, RIS, HIS, and/or other system to mark selected medical files and/or examinations as “signed” (block 1126). For example, after a client server system at a destination medical facility receives medical files and/or examinations from a source medical facility, the client server system can be configured to store the medical files and/or examinations into the medical facility's PACS, HIS, RIS, and/or image server systems using a direct HL7 and/or DICOM connection at block 1122. In certain embodiments, the client server system is configured to use an ORU, and/or equivalent message, system communication, or the like, to set a flag or status flag in the RIS, HIS, and/or PACS, or to trigger the RIS, HIS, and/or PACS at block 1126 to mark the recently stored medical files and/or examinations as “signed” or approved, reviewed, and/or analyzed so that the medical files, and/or examinations do not appear to a medical professional as unread and/or a new study. Marking the medical files and/or examinations as “signed” generally prevents the medical professional from reviewing already reviewed medical files and/or examinations, and allows the medical professional to use the medical files and/or examinations for historical review or comparison purposes.

Report Forwarding

In certain embodiments, the source medical facility is an emergency room, hospital, clinic, doctor's office, or the like, and the destination medical facility is a third party that provides outsourced radiology film interpretation/analysis and/or other medical services. For example, such third parties include without limitation NightHawk Radiology Services®, Virtual Radiologic, Quality Nighthawk, US Radiology On-Call, or the like. These third parties are generally employed by the source medical facility to read, analyze, and/or interpret the medical files and/or examinations generated at the source medical facility, and to transfer back such analysis, consultation, reports, images, or the like to the source medical facility for the medical professionals to review, analyze, and relay to the patient.

In this example, the medical files and/or examinations may need to be transferred or forwarded from the source medical facility to the destination medical facility wherein the transferred medical files and/or examinations are marked new, unread, unanalyzed, and/or unsigned at the destination medical facility. The client server system, in certain embodiments, is configured to automatically forward medical files and/or examinations to a destination medical facility based on a criterion, for example, a specific time period (low staffing period), periodic basis, in real time, or other basis. The criterion can also include but is not limited to being based on a specific time period (for example off-hours), based on staffing available (for example, scheduled staffing or real time assessment of staffing and/or current work load) at the medical facility, based on a specific examination type or specialty required, or any other criteria. Alternatively, the client server system can be configured to forward a file copy of or an electronic copy of all or substantially all images, medical files, and/or examinations received on a specific TCP/IP port to a destination medical facility. The medical files and/or examinations are marked new, unread, unanalyzed, and/or unsigned so that the third party medical professionals will be notified to review, analyze, and interpret the transferred medical files and/or examinations.

Generally, when transferring medical files and/or examinations, the destination medical facility may automatically import and/or display the medical files and/or examinations in a work list or the like, and mark the medical files and/or examinations as new, unread, unanalyzed, and/or unsigned. In certain embodiments, the client server system at a destination medical facility is configured to store the medical files and/or examinations into the medical facility's PACS, HIS, RIS, and/or image server systems using a direct DICOM and/or HL7 and/or other connections. The client server system can also be configured to use an ORU, and/or equivalent message, system communication, or the like, to set a flag or status flag in the PACS, RIS, HIS and/or other systems, or to trigger the PACS, RIS, HIS, and/or other system to mark the recently stored medical files and/or examinations as “unsigned” or unapproved, not reviewed, and/or unanalyzed so that a medical professional will be notified to review, analyze, and/or interpret the recently transferred and/or stored medical files, and/or examinations.

After reviewing, analyzing, interpreting, and/or signing the medical files and/or examinations, the client server can be configured to transfer the signed medical files, medical reports and/or examinations back to the source medical facility and/or other medical facilities. In transferring the signed medical reports and/or examinations back, the client server system at the source medical facility and/or at other medical facilities can be configured to use an ORU message, and/or equivalent message, system communication, or the like, to set a flag or status flag in a PACS and/or RIS, or to trigger a PACS and/or RIS to mark the medical files and/or examinations as “signed” if so desired.

Enterprise Master Patient Index

Enterprise Master Patient Index or Enterprise-wide Master Patient Index (EMPI), are Master Patient Indexes (MPI) or Patient Master Indexes (PMI), which link several smaller organization level MPIs together. In medical systems, a MPI is an index referencing all or substantially all patients known to an area, enterprise or organization. In certain embodiments, the client server systems and/or the main server systems are configured to connect and communicate with EMPI, MPI, and/or PMI systems to locate, search, retrieve, and store medical files, examinations, and/or other data.

Medical File Back-Up Module

In certain embodiments, medical facilities may require that medical files and other data be stored and/or backed-up at an off-site facility and/or at a third party service provider. Such requirements may be due to government regulations, disaster preparedness planning, cost/maintenance policies, and/or other medical facility policies. In certain embodiments, the client server system is configured to automatically forward medical files and/or examinations to a medical facility, third party service provider, off-site facility or the like that acts as a backup storage facility.

File and/or Message Conversion Module

In certain embodiments, the medical facilities may require that medical files and/or other data files that are transferred into and/or out of the medical facility be converted into a different file format and/or type so that the medical files, medical system messages, and/or other data files are compatible with and/or may be read by the systems and/or computer systems at the medical facility. In certain embodiments, the file and/or message conversion module can be configured to convert medical files, medical system messages, and/or other data files into other types of data file formats. In certain embodiments, the medical files and/or other data files may be converted by the client server system at the source and/or destination medical facility. For example, the medical files and/or other data files may be converted from a Microsoft® Word file to a WordPerfect® file, and/or the like. Other example file conversions include without limitation DICOM using JPEG2000 to DICOM using JPEG, DICOM to JPEG, Microsoft® Word to ASCII text, and the like. In certain embodiments, the file and/or message conversion module can be configured to convert, transform, and/or reformat system messages, for example, HL7 messages, into other message formats and/or types to be compatible with other hospital systems, for example, RIS, HIS, PACS, and/or other formats. This converting, transformation and/or reformatting process can be specific down to the individual character.

In certain embodiments, the file and/or message conversion module can be configured to determine the file format type by reviewing the extension name of the file and/or analyzing the contents of the files. The file and/or message conversion module can be configured to convert multiple medical files and/or other data files as an entire set.
